Moss is a common plant in Iceland. It grows abundantly in the mountainous region and is a special characteristic of Iceland’s lava fields. One of the most spectacular moss blanket is located on the southern coast of Iceland, over the Eldraun Lava Field.

The Eldraun Lava Field was created in one of the most devastating eruptions in recorded history. Over a course of eight months, between 1783 and 1784, the Laki fissure and the adjoining Grímsvötn volcano poured out an estimated 14 cubic kilometers of basalt lava and clouds of poisonous gases that contaminated the soil, killing half of Iceland's cattle and horses, and more than three-quarter of sheep. That year, nothing grew on the fields and no more fish could be found in the sea. The resulting famine killed approximately a quarter of the island’s human population.
